PATENT ROBERT LAING, OF MIDDLETON, ENGLAND.

Application filed May 29,

To all whom it may concern:

Be it known that 1, ROBERT LAING, a subject of the King of Great Britain, residing at Middleton, in the county of Lancaster, England, have invented certain useful Improvements in a Machine for Pressing Lines or Designs into Rollers, of which the following is a specification.

This invention relates to improvements in machines for pressing lines or designs into rollers used for imparting a lustre or-silky appearance to cotton fabrics of the type in which a knurling mill or series of knurling mills are employed as described in specificationbelong to British Letters Patent No. 6176 of 1907, granted to me, which press the lines or design gradually into theroller.

The said type of machine comprises generally, a bed with hearings to support the roller to be operated upon, a slide on said bed rendered longitudinally movable by a screw-threaded spindle, a stand on the rear end of said slide having a head in which is mounted the rear end of a frame carrying at its front end the knurling mill holder and a lever adapted to exert pressure on the knurling mill.

The object of the present invention is to improve the general construction of said type of machine, to simplify the manipulation thereof and thereby render same more efficient than hitherto has been the case.

A machine constructed in accordance with this invention comprises chiefly pressure levers which are each fulcrumed to said frame at a point between its front and rear end, means for balancing said frame, improved means for pressing said levers against the top of the knurling mill holder and the knurling mill against the roller to be operated upon, means for regulating the pressure exerted by said lever, means for the rotary adjustment of said knurling mill holder,

means for the angular adjustment of the knurling mill in relation, to the periphery of said roller and means for the continuous supply of lubricant to the knurling mill pivots and its bearing and also to said roller.

I attain these objects by the means illustrated in the accompanying drawings, in which- Figure 1 is an end view, Figure 2 a plan, Figure 3 a front view of the knurling mill head of the machine. Figures 4: and 6 are vertical sections and Figure 5 a plan of Figure 4:, of the knurling mill holder. Fig- Specification of Letters Patent.

pressure levers e are each fulcrumed to the knurling mill holder frame it at a point between its front andrear end and a lever 71 is also fulcrumed to the'frame it behind the The frame 71, is rigidly connected at the rear to a pivot pin 22 which is pivotally mounted in the stand 23 in steps 24the upper one of which can be adjusted byv the bolts 25. An adjustable counter Weight is is provided on the lever a to counter-balance the weight of the frame it and the parts carried thereon. The pivot on the stand 23 enables the frame it and the parts thereon to be lifted clear of the work and the lever 2' and counterweight 7c facilitate the lifting of the frame it and the lowering of the same into its correct working position in which it is rigidly secured by tightening the bolts 25 and thereby clamping the pivot pin 22 between the steps 24c. The pivot 22 therefore merely serves to raise the frame it and parts thereon clear of the work, and the counterweight 7a to reduce the effort necessary to perform this operation after the bolts 25 have been slackened the pressure of the knurling mills 0 on the work being obtained by the hereinafter described means.

The pivoted lever z' is prevented from falling by the bottom of the pivot end being made to abut against the base of the bracket to which it is pivoted.

The front end of each pressure. lever e and the front end of the slide f are coupled together by means of a spring influenced rod connection 9, Z, m, n formed in sections with ends suitably pivoted to the outer end of the pressure lever e and slide 7". The lower end of the top section Z and the upper end of the middle section m are coupled together by means of a right and left hand threaded union nut g, see more particularly Figures 1 and 7, while the upper end of the bottom section 72 has secured a cylindrical casing 0 at the top end provided with a screw-threaded cap 29 through which the upper end of the middle section we extends and which section together with the bottom section a can be longitudinally adjusted by the union nut g to either shorten or lengthen the rod connection and thereby vary the pressure of the pressure lever e on the knurling mill holder d as may be required for different work.

In the casing 0 is located around the middle'rod section m, a coiled spring 9 supported by a shoulder 1" formed onthe lower end of the latter and with its upper end bearing against the cap p on the casing 0 which spring imparts in said rod connection a certain amount of longitudinal elasticity and on which cap rests loosely a distance collar j with which when the knurling mill leaves the roller surface of the locknut '2' contacts, which prevents the knurling mills dropping onto the roller ends and thus prevents same being damaged. The middle rod section we is prevented from rotating by being formed with flats s engaging in a correspondingly shaped hole It in the cap '19.

The top section Z is preferably pivotally connected with the outer end of said pressure lever e by providing its upper end with a cross stud a adapted to engage in grooves 41 formed on the top. of the respective end of the lever 6 preferably forked, while the bottom section a i'sconnected to knurling mill slide 7 by means of an eye bolt w and pm or.

The method described of pivoting the top end of said rod connection to the free end of the pressure lever and the fulcruming of the latter to said frame, permits of readily disconnecting said rod connection from the pressure lever and also of removing the latter when required.

The periphery of the flange e at the upper end of the bush 4 located in the frame it is formed with a worm wheel 2 arranged in gear with a worm 3 mounted on the frame 71. whereby the knurling mill 0 can be rotatably adjusted in relation to the periphery of the roller 5 as may be required and locked in position by the set-screw 4.

The top of the frame la is provided with a pointer 5 and the top of the bush g vwith a graduated circular scale 6 whereby the amount of the adjustment can easily be read and thus readily determined.

To ensure the knurling mill 0. always operating with its periphery parallel with the periphery of the roller 7), it is made angularly adjustable on the head of the knurling mill holder (Z in order to permit compensating for any difference in the rel-V ative positions of either of said peripheries. This angular adjustment may be effected by forming thehead of the holder in which the knurling mill 0 rotates in two parts 9 and 10, the part 10 being pivoted to the part 9 say by a bolt 8, as in the present instance. The part 9 carries on each side of its stud S a set screw 7 adapted to bear against the top of the part l0 by means of which the angle at which the knurling mill 0 is to rotate, can be readily varied.

To vprevent the knurling mills c from leaving their bearings 13, when the head end is lifted or the knurling mills pass the roller ends flat springs 11 are secured to the knurling mill head part 10 which bear against the knurling mill pivots 12 and thus support the knurling mills.

In order to permit of automatically supplying the knurling mill pivots 12 and bearings 13 and roller Z) to be operated upon, with lubricant, two superposed vessels 14, 15 are employed, the upper one 14 of which is suitably attached to front end of the frame it and the lower one 15 to the front side of the knurling mill bearing or head 10. The latter vesselis arched to facilitate placing of the knurling mill 0 in the forked bearing-13 of the holder dand by a pipe 16 furnished with a tap 17 is connected with upper vessel 14. The lower vessel 15 has also two pipes 18 extending from the inner side thereof, fitting intocorrespondingly located holes 19 formed in one side of the forked bearing 1 13 leading to grooves 20 therein, while the bottom is furnished with pipe 21 extending to near the periphery of the roller 5 to be operated-upon.
